BACKGROUND OF THE INVENTION
The present invention relates to a road intersection structure, and more particularly to a road intersection structure intended to improve a walking environment.
[0002]
[Background]
In general, as shown in FIG. 7 and FIG. 8, the structure of a road intersection is known.
[0003]
The intersection shown in FIG. 7 indicates a plane intersection state, and the plane intersection 104 is configured by the first road 100 and the second road 102 intersecting in plane on the ground.
[0004]
The first and second roads 100 and 102 are provided with three lanes of a left turn and a straight lane 106, a straight lane 108, and a right turn lane 110 in order from the left side at the entrance of the plane intersection 104, and a straight lane 112 as an opposite lane. There are a total of 5 lanes with 2 lanes.
[0005]
The traffic route of the vehicle in the plane intersection 104 is in a state indicated by an arrow in the figure, and the traffic of the vehicle is arranged by a signal.
[0006]
The pedestrian crossing 114 is provided over the entire width of the first and second roads 100 and 102 around the plane intersection 104.
[0007]
The intersection shown in FIG. 8 indicates a three-dimensional intersection state, where the first road 116 and the second road 102 intersect in a plane and a part of the first road 116 is an elevated road 118. It is a three-dimensional intersection 120.
[0008]
Specifically, the first road 116 has a total of four lanes consisting of a left / right turn and straight lane 122, a straight lane 124, a straight lane 126 as an oncoming lane, and a straight lane 128 from the left side. The straight lanes 124 and 126 are elevated roads 118, which can alleviate traffic congestion.
[0009]

[Problems to be solved by the invention]
In the structure of the intersection in FIG. 7, vehicles in all lanes of the first and second roads 100 and 102 enter the plane intersection 104, so the signal waiting time becomes longer and traffic congestion occurs. It becomes a bottleneck that is the main cause.
[0013]
In addition, since the pedestrian crossing 114 is provided over the entire width of the first and second roads 100 and 102 around the plane intersection 104, it must cross a five-lane road, and the walking distance is long. In order to go from the predetermined block to the block opposite to the diagonal, it is necessary to wait for the signal twice, which takes time and is inconvenient for the pedestrian.
[0014]
Further, the plane intersection 104 becomes a vehicle-dedicated space where pedestrians cannot enter, resulting in alienation of pedestrians and division of the greening network.
[0015]
In the structure of the intersection shown in FIG. 8, the straight lanes 124 and 126 of the elevated road 118 have no signal and can contribute to traffic congestion mitigation. As in the case of FIG. 7, it becomes a bottleneck that is the cause of traffic congestion.
[0016]
In addition, the walking distance of the pedestrian crossing 114 is long, and there is inconvenience of pedestrians such as waiting for two traffic lights to go to the street opposite to the diagonal. The division or the like occurs as in the case of FIG.
[0017]
The object of the present invention is to eliminate traffic congestion due to intersections, eliminate inconvenience of pedestrians due to long pedestrian crossings, make pedestrian-priority barrier-free spaces that do not rely on traffic lights in the intersections, and further greening The object is to provide a road intersection structure that can be networked.
[0018]
[Means for Solving the Problems]
In order to achieve the above object, the road intersection structure of the present invention has one of the first road and the second straight road as an overpass at an intersection where the first road and the second road intersect. Forming the other with at least one of an elevated and a moat split,

[0035]
Similarly, the second road 12 has two opposing straight lanes 24 and 26 which are straight vehicle sections at the center, and right and left turn lanes 28 and 30 on both sides thereof.
[0036]
Then, the vehicle straight part of the first road 10, that is, the two straight lanes 16 and 18 are the elevated road 32, and the vehicle straight part of the second road 12, that is, the two straight lanes 24 and 26 are the moat split road 34. The intersection 14 is formed.
[0037]
An infrastructure space 35 is provided below the moat split road 34.
[0038]
Further, a floor slab 36 is installed on the upper part of the moat split road 34 to form an above-ground part 38, thereby forming the intersection part 14 having a three-layer structure.
[0039]
In the ground portion 38, a flat walking space 42 including a slowing region 40 for turning right and left of the vehicle is formed on the ground surface.
[0040]
The slow region 40 has a left-turn vehicle passage 44 and a right-turn vehicle passage 46.
[0041]
The left-turn vehicle passage 44 is located outside the right-turn vehicle passage 46, and from the right-left turn lanes 20, 28 of the first or second road 10, 12 to the right of the second or first road 12, 10. The left turn lanes 30 and 22 can be turned left.
[0042]
The right-turn vehicle passage 46 is formed in an annular shape inside the left-turn vehicle passage 44 and has a rotary type. The right-turn vehicle lane 20, 28 on the first or second road 10, 12 goes straight and is circular. It is possible to enter the right turn vehicle passage 46.
[0043]
Moreover, in this right turn vehicle passage 46, it is possible to make a right turn to the right or left turn lane 22, 30 side of the first or second road 10, 12 by making a right turn at the first corner. By making a further right turn at this corner, a U-turn can be made to the right or left turn lanes 30, 22 of the second or first road 12, 10.
[0044]
In addition, a square space 48 is formed at the center of the annular right-turn vehicle passage 46 so as to form an exchange space for people leading to the activation of the surrounding area.
[0045]
Then, a sidewalk 50 for the walking space 42 around the annular right-turn vehicle passage 46 and a crossing for the left-turn vehicle passage 44 extending from the sidewalk 56 of the first and second roads 10 and 12 to the sidewalk 50. The sidewalk 52 is formed toward the square space 48, and the pedestrian crossing 54 for the right turn vehicle passage 46 extending from the sidewalk 50 to the square space 48 is formed.
[0046]

[0047]
In addition, the trees 58 are planted in the sidewalks 56 on both sides of the first and second roads 10 and 12, the square space 48 in the walking space 42, and the sidewalks 50 so that a greening network is achieved.
[0048]
By providing the vehicle deceleration means 60 at least at the entrance of the slow-moving area 40 for turning right and left of the vehicle, for example, at the entrance to the intersection 14 of the right and left turn lanes 20, 28 of the first road 10 and the second road 12. In this way, slow travel in the intersection 14 can be ensured.
[0049]
As the vehicle deceleration means 60, for example, by providing a hump such as an unevenness or a tile pattern at the vehicle entry portion, it is possible to promote slow driving.
[0050]
In addition, the vehicle deceleration means 60 is not limited to the vehicle entry portion, and provides a bon elf over a predetermined range of the slowing region 40, specifically, the left turn vehicle passage 44 and the right turn vehicle passage 46, to provide a travel path of the vehicle. It can be decelerated by bending.
[0051]
Furthermore, in this Embodiment, as shown in FIG.5 and FIG.6, the intelligent traffic system (ITS) is installed in the slow region 40. FIG.
[0052]
Specifically, an ITS speed limit receiving device is mounted on the vehicle, an ITS speed limit transmitting device 62 is disposed at the vehicle entrance of the slowing region 40, and an ITS speed limit canceling transmitting device 64 is provided at the vehicle exit from the slowing region 40. The vehicle is placed, and a speed limit is applied to the vehicle that has entered, and the vehicle travels in the slow region 40 at a predetermined slow speed, and the restriction is released at the vehicle exit.
[0053]
In this manner, the straight lanes 16 and 18 of the first road 10 are the elevated roads 32, and the straight lanes 24 and 26 of the second road 12 are the moat split roads 34, so that no signal is sent to the vehicle straight ahead and the bottle The occurrence of the bottleneck can be eliminated and the traffic jam can be eliminated.
[0054]
Further, it is only necessary to form the right and left turn portions of the vehicle on the ground surface. By making the right and left turn portions into the slow running region 40, the walking space 42 including the slow running region 40 can be formed at the intersection portion 14, and By forming the walking space 42 flat, it is possible to form a pedestrian-preferential barrier-free intersection 14 without a signal.
[0055]
Moreover, since the pedestrian crossings 52 and 54 are not provided over the entire width of the first and second roads 10 and 12, but are designed to cross toward the open space 48, the walking distance can be short, There is no need to wait for a signal twice to go diagonally across the street.
[0056]
Further, the right turn vehicle passage 46 in the intersection is a rotary type, a square space 48 is formed in the center, and trees 58 are planted in the square space 48 and the sidewalk 50 around it, thereby improving greening. It is possible to form an open space that promotes the exchange of people that leads to the activation of the surrounding area.
[0057]
Thereby, for example, in an urban area, the efficiency and amenities of the urban area can be improved and the overall urban environment can be improved.
[0058]
In addition, a vehicle-priority space that does not depend on signals by providing vehicle deceleration means 60 at the vehicle entry section to ensure reliable deceleration, or by installing an intelligent transportation system in the deceleration area 40 to control vehicle speed and prevent collisions. Can be formed in the walking space 42.
